ADJUSTABLE CYLINDER-LOCK.

Specification of Letters Patent.

Patented Sept. 1, 1908.

Application filed February 15, 1908. Serial No. 416,039.

To all whom it may concern:

Be it known that I, HENRY G. VoiGHT, a citizen of the United States,residing at New Britain, Hartford county, State of Connecticut, haveinvented certain new and useful Improvements in AdjustableCylinder-Locks, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in cylinder locks, the object beingto provide simple, effective and durable construction withoutsacrificing to quality, strength or durability.

Another object of the invention is to provide a simple and effectivemeans for adjusting the lock whereby it can be connected to lock casesfitted to doors of different thicknesses.

In the accompanying drawing Figure 1 is a side elevation of the completedevice, the parts being shown at approximately their minimum adjustment.Fig. 2 is a similar view, the parts being shown at approximately theirmaximum adjustment. Fig. 3 is a longitudinal vertical section of Fig. 1,certain parts being shown in section. Fig. 4 is a horizontal section ofFig. 2, certain parts being shown in elevation. Fig. 5 is a view of theinner end of the lock. Fig. 6 is a view of the outer end. Fig. 7 is asection on the plane of the line XX Fig. 3, looking to the left. Fig. 8is a section on the same line, looking to the right. Fig. 9 is a view ofa de ,tail of construction, showing the method of its connection.

1 is the face plate of disk-like form and constructed in any desiredway, the said plate being provided if desired, with an ornamental scalp,as shown in Fig. 3.

2 is the cylinder casing.

3 is the plug.

4 is the pin tumbler casing.

The forward end of the cylinder casing 2 takes a circular seat in theface plate 1, while the forward end of the tumbler casing 4 has arivet-like extension 5, whereby the parts may be secured againstseparation or independent rotation, thereby forming a frame of the parts1, 2 and 4. The upper part of the tumbler casing 4 is preferablyenlarged, as best seen in Fig. 8, while the lower part of the cylindercasing 2 is likewise enlarged. The external-wall of these enlargedportions is suitably shaped to receive thereon a hollow cylindricalshell 7, the inner wall of the shell being screw-threaded thereon, sothat by turning said shell 7 relatively to the face plate 1 these partswill move toward or away from each other. The enlarged portions of thecylinder and tumbler casings constitute an effective support for thehollow shell, dispensing with the necessity of any guide pins or thelike. The rear end of the hollow shell is provided with a closure or endplate 10, but in this form said end plate is preferably held againstrotation therewith.

1717 are recesses in the opposite sides of the hollow shell 7 near therear end. These recesses are formed by striking in the metal, so thatthey at once provide means to receive the end of a set screw carried bya lock case,

with which the cylinder lock may be connected, and also provideabutments or shoulders to support the end plate 10 at its inner side.The extremerear edge of the shell 7 may be curled over at one or morepoints, as shown at 7 a 7 a F ig.- 5, to hold the end plate 10 in place.66 are bosses projecting laterally from the tumbler casing, said bossesbeing bored longitudinally to receive the dowel pins 1111, which arecarried by the end plate 10. IVhen the parts are assembled, obviouslythese dowel pins 111l prevent the end plate 10 from turningindependently of the face plate 1.

14 is a rollback rotatably mounted in the end plate 10. Projectingforwardlyfrom the hub of this roll-back are pins 1212, which make atelescopic engagement with the key plug 3.

3 is a cap at the inner end of the key plug to hold it in place.

15 is a bolt slidably mounted on the end plate 10 and adapted to bemoved in and out to interlock with a locking shoulder 16 at the end ofthe hollow shell 7. When it is de sired to adjust the shell 7 on theframe, the bolt 15 is retracted, freeing the shell. The latter may thenbe turned freely until the desired adjustment has been secured. As theshell moves in and out, the dowel pins carried by the shell of theroll-back move in and out freely in their respective bores. When thedesired adjustment has been effected, the bolt 15 is moved outwardly andmay be locked in said position by a screw '18.

It should be understood that the terms roll-back and keyplug areconventionally employed and are intended to include the substitution ofequivalent devices.

It should also be understood that the particular tumbler constructionemployed is immameans to permit the shell section to be rotated foradjustment on the frame section without disturbing the alinement of theplug and roll-back.

2. In a cylinder look, a frame, a rearwardly projecting threaded shellsup )ort, a hollow shell section havinga rotatablet 1readed connectionwith said threaded support and adapted to be adjusted to and. frothereon by rotation, said shell section having a non-rotatable; back, aplug carried by the frame, a roll-back mounted on said shell back andadjustably connected with the plug, and means to lock the threadedconnection of the a shell section against rotation relatively to theframe section.

3. In a cylinder look, a frame, a rearwardly projecting threaded shellsupport, a hollow shell section having a rotatable threaded connectionwith said. threaded support and adapted to beadjusted to and fro thereonby rotation, said shell section having a non-rotatable back, a plugcarried by the frame, a roll-back mounted on said shell back and adjustably connected with the plug, and means to lock the threadedconnection of the shell section against rotation relatively to the framesection, said locking means being carried by said. shell back anddetachably en gaging said rotatable shell connection.

4. In a cylinder lock, a frame including a rearwardly extending threadedshell support, a hollow shell having a portion correspondingly threadedand rotatably mounted thereon, a plug in said frame, a rotatableroll-back and a non-rotatable support therefor, ad justable means ofconnection between said roll-back and plug and between said rollback,support and frame.

5. In a cylinder lock, a frame including a rearwardly extending threadedshell support, a hollow shell having a portion correspondingly threadedand rotatably mounted thereon, a plug in said frame, a rotatableroll-back and a non-rotatable support therefor, adjustable means ofconnection between said roll-back and plug and between said rollback,support and frame, said roll-back and support being connected with saidhollow shell connection for movement to and fro therewith.
